Pin holes in paint?

[rayndogg]

WHY, WHY, WHY?!?! I have been having this problem all build season and still now what gives. Everything I paint no matter if it's primer or top coat I'm getting little, I mean tiny, tiny pin holes everwhere. I took all the plugs and tried sanding them all out. Pretty much had to strip them all down and repaint. But still getting the pin holes. Now I have some that didn't, but when I applied the top coat is got them or the paint lightning bolted (crackled). I soak them in Spar/MS let dry for a week or so lightly sand. Prime with 1-2-3 and lightly sand top coat Painters CHOICE Semi-Gloss or flat white. Besides sealer all the paint is a Rustoleum product except to airbrush paint, but i can't seem to get to that point..... Lost of time being wasted here I'm talking like 30 plus plugs I'm ready to toss the who mes in a pit fire...

Thanks Rene

How are you mixing it? Infusing air with a drill powered mixer? Mix with a stick by hand slowly with figure eights. Let sit for 45 mins before painting??

Rattle can primer and top coat. Don't apply top coat for at least one week. From time primed.

i would try the same paint scheme on different materials
or different woods
to see if it's something built into the surface.... or not
and then compare...

this helps to rule OUT certain things
when you have that control group
to figure out whats causing it

I was just thinking.. the only thing that I have changed when this all started was the Spar I was running low so I purchased a new qt. with qt. of Mineral Spirits. I wonder if that's my problem ?. this batch is even darker than all the other batches I;ve used in the past.

It happens no matter the wood type I use Pine, WRC, AYC

ahhh ha there's your guilty party

when your house painting (namely walls)
the only place paint won't stick is any spot
that got splattered by cooking oil or anything oily
unless you scrubbed it with TSP solution and that stuff
is mean as hell ...it'll burn your skin if you don't wear gloves

that is what got me thinking that somehow there's an oil
impregnating the wood somehow
but since you hadn't mentioned the mineral spirits i didn't
think it was in the MIX

i would switch solvents and see if the problem vanishes

If you are getting "orange peel" in your primer, I would look into your sealing mixture. Something is not drying enough to allow the paint to flow evenly across the surface. Rattle cans atomize the particles pretty evenly, and if it happens summer and winter, it is not an ambient temperature problem. Do a test on a blank that is not sealed and see if you are still getting the orange peel. That will isolate the problem to the sealer, or eliminate that as the problem.

here's your problem....never put oil paint on top of water base paint..your 1 2 3 is water base....painters touch is oil.....remember this rule....you can put water based paints on oil but not oil on water based..never could... and use flat paint and stay away from anything gloss as a top coat if your planning on using other colors on top of it.

true what you are saying. the only thing is this is happening when I prime.

Good advice from grapes, when you see pin holes that is a chemical that has not flashed off yet escaping or a chemical reaction between paints or paint and sealer. I had that problem when i first started.

Make sure your sealer is dry, dont use kilz or rustoleum primers they killed me i now ise Valspar but unfortunately they only have paint primer mix now...
